Hi all, In a few days My 370 will be put ashore for the winter. Since this is the first time for me I have a question about the mast. The big issue is: will I leave the mast on or have it taken off. I prefer to leave it on, since it is much easier, quicker and cheaper. Also the risk of damaging something while taking it of and putting it back is avoided this way. On the other hand with the mast on the ship will catch more wind. Any advise??? Regards, Ron |

Ron,
I would take it of because of the forces to the polyester while standing on the bok (don't know the English word). I have seen pictures of boats with a waved hull after they took the boat back into the water.

wenn your boat is Epoxy you have to take it off.
Wenn it is GRP you can keep it on the boat .
Just take care your cradlle is strong and can take care off the boat with the mast on.
I took off my mast , it quite some work but is OK .
I did put the mast off because I had to do some work on it.

Marcel, I had the same diskussion on the Swedish Hanse site a while ago but no one never mentioned epoxy as a reason to take of the mast. Can you elaborate why epoxy boats need to be masted off?
As for Zeester this is our first time we lifted up the boat and I have lot of "stress" with not knowing waht is the best way. Many of the boats in our marina have their masts on but off course, they are not epoxy.

| I have the same question as Marco, what does epoxy have to do with taking the mast off? This topic was discussed extensively in another thread within the past couple of months and this was never mentioned that I can recall.... Steve |

It was specialy mentioned wenn I was buying my boat.
Therefore we bought a GRP hull.
The say the epoxy is so stiff it wil not bend but break wenn there is a lot of power on the points the boat leans on the hull , ofcourse the boat must stand on its keel but the sidewards forces are huge wenn there is a lot of wind.
Epoxy is strong but since GRP is flexing more it can handle the sidewards powers.
I have seen X yachts at the yard I come often witch have been on a cradle withe the mast on and those hulls are GRP but under the watherline they are also sandwitch.
The laminate hase been destroyd on the places it did lean on the craddle.
That is why I should never put a sanwich baot on a craddle whit the mast on, wheather it is Epoxy or GRP.
greetngs Marcel

In our harbour we have 3 Hanse 370. Mine (GRP) and another 370 (epoxy)were lifted with the crane last and this weekend. The Harbourmaster first lifted last week the epoxy version. When i came to the crane with my boat he first asked if i have a epoxy hull. He was happy to hear that i have a GRP boat. He told me that the epoxy hull was very difficult to handle. My GRP build hull felt much more stiff than the epoxy one - That is what he told me....................
hmm......
BTW i would always take the mast of in wintertime when the boat is lifted on land. ------------- Blake 370

@Marcel: I was told that epoxy is much more durabel than GRP when it comes to forces on a larger are but very sencitive to force by a small point. Therefore it is neccessary to have bigger contact area on the cradle arms than normal. I havent heard anything else so now you really have me puzzeled here. Also, too late to do anything so I'll have to see what happends through the winter. Will keep you all posted :)
Is ther anyone so far who has experienced cracks or similar on their hull after a winter on land ? ------------- "Älva" Hanse 370#671 Stockholm, Sweden http://www.wesailhanse.se" rel="nofollow - www.wesailhanse.se big wheel, deep draught iron keel, 3 cabins,Yanmar 3JH4E, Sparcraft rig. |

I have owned sailboats for the past 25 years beginning with an O'Day 25, Pearson 33, Pearson 34 and my Hanse 370e. Both Pearsons and my Hanse were always stored mast up. I haul by mid October and return to the water by Mid April. All boats were supported by the cradle (or jack stands), not the keel. Once placed on land the keel is "blocked", that is, support is placed under the keel so it doesn't just hang as dead weight. This is my 4th winter with my Hanse on the hard, outdoors, mast up, and shrink wrapped. I've not experienced a single problem. Now, I'm sure that there are those that will agree and those that will disagree with my method. However, remember that what you hear may well be different from what you experience. My information is based on real life experience in a cold harsh winter environment. ------------- Silversailor South Haven, MI USA S/V Legacy 2010 Andrews 28 |

A few years ago, we took the boat out of the water for some painting works with mast up. We slept in the boat. In the night, some wind comes, no storm. It was really not nice to be in the boat and I was surprised how much the boat moves. Yes a boat is elastic but I wouldn't like to see my boat on shore in winter storms.
Since that time I prefer to leave the boat in the water - mast up. In my opinion thats the most savest place for a boat in winter if the harbour is prepared for that. In our harbour in Netherlands about 150-200 boats will stay in their element. ------------- BR Ralf, Ex. 'a mare' H370 |

Ralf, If I could I would. That is, if I could leave Legacy in the water over the winter I would. However, our river freezes over so I would need to operate a "bubbler" to maintain some open water around her hull. Since I'm 1200 miles away during the winter, I'm not comfortable relying on some electrical devise to maintain my boat. ------------- Silversailor South Haven, MI USA S/V Legacy 2010 Andrews 28 |

But frozen water should be no problem for the boat if the water doesn't move. In our habour they use the bubblers but not in all sections.
The harbourmaster told me, in 30 years only one time they had a problem at one boat, cause the owner didn't fill the valves with antifreeze.
The photos are taken at January 2009, all at the same day.

Unfortunately, my slip is directly on the river, not in a protected marina such as appears in your pics. Fortunately, the slip is directly in front of my condo so 15' from my living room I'm at my boat in Spring, Summer and Fall.

I have the same experience of Silversailor. 3rd winter ashore with my hanse 400e, mast up, no problem (and 15 winters ashore, mast up, with my previous boat. But, of course, she was grp and no sandwich ;-)) best J. |

Directly on the river I wouldn't let the boat in the water. Good decision to take it out. ------------- BR Ralf, Ex. 'a mare' H370 |

Hi, I decided to have the mast off. Yesterday I removed the sails and sprayhood, between the showers and blasts of wind. The removal of the mast will be done next week. Regards, Ron |
